📡 Source: NEUTRAL
📊 Confidence: 70%
The source presents scientific findings, which are generally considered reliable but should be interpreted within the broader context of ongoing climate research.

Antarctica's glaciers were changing long before satellites, weather stations or cameras captured their transformations, and they left behind clues. Along Marguerite Bay on the western Antarctic Peninsula, ridges of rocks and debris mark former glacier margins. For decades, scientists lacked direct evidence about when many of these ridges formed.
